Answer:
To create a medium for the reaction since it occurs in acidic medium
Answer:
3.00 × 10²³ atoms H
Explanation:
Step 1: Given data
- Atoms of oxygen in water: 1.50 × 10²³ atoms
- Chemical formula of water: H₂O
Step 2: Calculate the number of atoms of hydrogen
According to the chemical formula of water, the atom ratio of H to O is 2:1.
1.50 × 10²³ atoms O × 2 atoms H/1 atom O = 3.00 × 10²³ atoms H
Metals are lustrous, malleable, ductile, good conductors of heat and electricity. Other properties include: State: Metals are solids at room temperature with the exception of mercury, which is liquid at room temperature
